"In 2020, the speed of network services will be 10 times faster than today and the level of network services will be improved by 10 times. Future networks will even be able to map out the spread of diseases to effectively contain the spread of viruses(...) I am most definite that this future will bring a broader and greater change to our world than the mobile era.”

Korea’s policy also focused mainly on fiber infra, but we
faced a challenge of upgrading the copper-based network

※ GAM : G.hn Access Multiplexer / GNT : G.hn Network Terminal
With ADSL
• No frequency overlapped with G.hn (No interference)
With VDSL
• A few frequency overlapped with G.hn (3.5 ~ 30MHz)• G.hn uses the lowest power, interference to VDSL is low
G.fast uses higher power level so interference to VDSL is high • G.hn supports PSD shaping for VDSL frequency (Power level of
VDSL frequency is configurable)
Deployed GiGA Wire in the building with existing VDSL equipment provided by three Korean operators without any impact to legacy services via the use of low transmission power
